It adjusts the first stage and also total length of trigger travel. Turn screw B clockwise to reduce travel. Screw C is the rearmost screw in the trigger blade. It adjusts the second stage by changing the sear engagement distance how much the both sears overlap each other when the 1st stage is taken up. If the first stage screw B is incorrectly set, adjusting screw C will have no effect.
When you only want to increase or reduce the trigger pull weight a little bit you only need to adjust screw A. Screw it clockwise for a heavier trigger pull and counter clockwise for a lighter pull. You cannot go wrong with this screw. Adjust it in and out as you like, you will see it is easy to get back to the desired or original setting.
Adjusting the 1st and 2nd stage of the trigger is where it gets more difficult as each of the individual screw settings will have an effect on ALL of the settings for weight and length and sear engagement. In other words: when you adjust screw B it will have an effect on the settings of screw C and vice versa. To properly adjust the trigger first thing to do is to set the trigger to go off on the first stage only.
They appreciate that the true requirement for hunting is the muzzle energy produced by an air rifle, not the maximum muzzle velocity. Most hunters will use domed lead pellets with a weight of 14 Grains or more. This is an excellent power output from what is a small and compact air rifle.
The Lothar Walther barrel of the TDR clearly was not happy with light weight pellets of 7 grains and below. That could be the case if we genuinely thought that hunters would be interested in shooting the light weight pellets in our standard test suite. But remember that this is a near-pistol-sized takedown model and these numbers become a lot more impressive!
As is our standard practice, the HAM testers did not adjust the trigger on the TDR, the pull weight and overall feel seemed ideal to us, just as it was set in the Hailsham, UK factory.
The first stage is rather short and light. The second stage is heavier, but very predictable and consistent. Engaging this safety blocks operation of the trigger very effectively with just a short travel of the safety button. However the bolt handle does have to be pulled right back — beyond the click — otherwise the trigger will not be set, even though a pellet has been loaded into the barrel. The other claim made for the Air Arms S TDR air rifle is that it can be taken down and reassembled many times without the scope loosing zero.
Again, we agree. The trigger pull weight was almost exactly constant at 1 Lb 12 Oz, straight out of the box. Trigger pull weight felt — and measured — almost perfect consistency. As already discussed, accuracy was also consistently good with lead pellets of 14 Grains and above weight. Unusually, Standard Deviation tended to be higher with the heavier, more accurate pellets and lower with the lighter, less accurate ones. This, in combination with a relatively short barrel, means that the gun is not the quietest.
It seems significantly less noisy than a Benjamin Discovery — for example — but obviously waaaaay louder than our benchmark for silent shooting, the Benjamin Marauder. As a dedicated hunting air rifle, this noise level may not be an issue for many shooters, however. The choice of optics is left to the purchaser and this is a sensible decision. This Hawke scope is not too big and balances nicely on the TDR — in our opinion.
This works well, as does the standard mil-dot reticle and the positive, click-adjustable elevation and windage turrets.
An FAC version was introduced around the same time as the S This was initially the same basic rifle with a few tweaks, such as opening the transfer port and using a heavier spring. Longer cylinders and barrels were used as well as a new striker and valve system. Due to loudness of the FAC version, and with it being considered too long to add a moderator, a shroud was added and this was fixed to the end of the cylinder.
With the barrel band now being redundant, 2 stock in-fills were used to fill the gaps resulting from its removal. This version had a black, realtree cammo or Mark Bromley airbrushed cammo pattern stock and action, as well as a matching silencer, there was the option to have a matching x40 BusHnell Banner scope with mounts.
Since then I've bought the air tank, put in excess of pellets through it, the rifle, not the tank , all at varying sized targets and cannot fault it's accuracy, the misses were my errors , build quality, and I've had no problems with the magazine action. It's been secure and indexed perfectly. Delighted with the whole package. Air Arms magazines are usually very reliable.
Have you tried another magazine? You might find it'll work with another mag and if so, it's the indexing mechanism at fault. It might be the little brass actuator that's playing up. Have you called Air Arms?
They're very helpful and I'm sure you'll get all the help you need. Let us know how you get on. I have had an air arms s for a year and after 11 months I had to have the seals replaced which to long however since I got it back I have shot 7 rabbits 2 doves 3 crows 6 squirels and 2 pigons this gun has outstanding accuracy and would recommend this gun to anyone looking for an accurate hunter without a large price tag!!
I bought new gun in oct Had the same problems as above magizine popping out when cocking. Under powered, chroned at Not so good for rabbits. Sent it back to air arms under warranty. I bought a S-4oo from euro guns, fired less than shots before said gun started leaking air. I then moved on to shotgus and sold the air rifle to a friend, the friend only had it a month before it started leaking off air yet again, this gun as had less than a tin of pellets though it and it as had to go back for repair 3 times.
This is the first PCP air rifle I have ever owned. I've read the postings on the air arm S and all I can say is there is nothing like it!!! I was able to sight my S in with 4 shots. My back yard is only 75'. I started out shooting poker chips then went to straws then to golf tee's they were no match for this rifle so I set tooth picks up and was able to hit all 4 in 5 shots. I have spring rifles that don't even come close but still love them. As of now I will never get rid of this S I'm a believer in the Air Arms Rifles.
Best, HPH. Sadly my S Classic failed on it's first outing. I bought the rifle at Christmas time ' After the Christmas madness I got the rifle out for it's first session in the field on new years day.
I zeroed the rifle with the first magazine and was smiling from ear to ear at my new rifle's handling and accuracy. On the twelfth shot I ever fired with this brand new rifle a valve between the air reservoir and breech did not close and all the air vented down the barrel in about five minutes.
I re-cocked the action. I reconnected it to my air cylinder and tried to top it up. Nothing stopped the venting. It was sent back to Air Arms for repair. A disgraceful two months later how many new rifles can Air Arms make in two months I wonder? I was pleased to see the rifle back but was upset it took two months to get it sorted.
Unfortunately it wasn't sorted. It failed again in exactly the same way, this time after a couple of hundred shots and a couple of refills. Once again the shop sent the rifle back to the manufacturer under warranty.
They promised it would be back much sooner than last time.
